ORNAMENT FOR THE CAPS OF RADIATORS.

Specification of Letters Patent. 7 D 21 1920 Application filed April 23,1917. Serial No. 163,856.

This invention relates to improvements in ornaments for the caps ofradiators, pertaining more particularly to an ornament adapted to berotated on a vertical axis by the advancing movements of the motorvehicle on which the ornament is secured.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings,

Figure 1 is a view in side elevation of a device that embodies featuresof the invention;

Fig. 2 is a view of a blade thereof;

Fig. 3 is a View in detail showing one method of attachmentto thestandard;

Fig. 4 is a view in elevation of a modification of the device;

Fig. 5 is a view in elevation of a further modification of the device;

Fig. 6 is a view in detail of a modified form of blade;

Fig. 7 is a view in detail taken 011 or about line VIIVII of Fig. 4, and

Figs. 8, 9 and 10 are views in detail showing pivot supports for the fanblade.

As herein shown, a base '1 is adapted to be secured by bending intoengagement with the cap 2, indicated in dotted lines, Fig. l, of thefill opening of a radiator. This connection may be eflected by bendableprongs 3 that can be inturned under the margin of the cap. An uprightspindle 4 is secured to the cap 1 by suitable soldering, brazing or thelike, and affords a pivotal support for a two bladed vane 5 which may befluted or otherwise arranged to carry an ornamental design, such as aflag or the like, with the blades crowned or made convex longitudinallyin opposite directions, that is, with reverse curvature on the oppositesides of the spindle, as indicated in the plan View in Fig. 2, so thaton movement through the alr the blades revolve. An upper marginal flangeon the concave side of each blade directs air downwardly toward the cap.r

As a matter of good mechanical constructown, where the device is put upas indicated in Fig. 1, it is advisable to have the cap arranged with arounded bearing rib 6 (see Fig. 3) and with a corresponding bearingmargin indicated at 7 on theblade so as to allow for movement. Or asindicated in Fig. 4, the base may be a strip 8 adapted to be securedaround the fill opening flange by bendable tongues 9 engaged to andfolded back over the slotted ends of the strip. In such instance theremay be an upright rod 10 with the lower portion bent laterally andsecured to the strip, and with a split tube 11 secured on the upper endthereof in which the roughened body 12 of an upright spindle 13 may beinserted as a pivot for the blade 14.

Or,asindicated in Fig. 5 the spindle 15 may have set nuts 16 by which itmay be secured in an opening in the cap 18 with the upper reduced endportion 19 of the spindle passing through an upper ear 20 of the blade21, the end being afterward flattened to the spear head form indicatedat *22 to retain the blade in position. Or the spindle may be tubularwith the lower exteriorly screwthreaded portion 26 and a reducedinserted screwthreaded portion 23 which may practically be a machinescrew, forced into the tube. This latter construction enables the bladeto move upwardly under the influence of air which it forces downwardlyand thus relieve the bearing on the base so as to greatly reduce thefriction.

As shown in Fig. 5, the ornamental configuration of the vane ispreferably such as to produce the appearance of a fluttering emblem asthe car travels forward, and, in order to prevent more or less blurringof the emblem-especially where the emblem includes approximatelyhorizontal stripe configurations-I prefer to locate the emblemconfiguration on but one of the wings of a face of the vane, this beingthe trailing wing face on each face of the vane. For instance, in Fig.5assuming the view to represent the vane appearance from a position infront of the radiator-the advance of the car will cause the vane totravel in a counter-clockwise direction on its axis, the unmarked wingface thus being the advance face, the emblem-carrying wing face trailingso that the Configuration gives the appearance of an advancing flagfluttering as it advances. By omitting the representation on theopposite wing face, the illusion is not disturbed by the presence of aduplication of emblem'representations. This relation is, of course,present on the opiposite face of the vane from that shown in ig. 5, withthe result that each wing has one of its faces carrying the emblemrepresentation with the opposite face of the wing free from suchrepresentation, the dimensions of the representation on each vane facebeing included within the face of but one of the wings.

The illusion thus created is enhanced by the use of the flanged portions17 which tend to produce a pocket effect on that face of the vane whichis subjected to the air pressure during the advance of the car, therebyinsuring that proper rotation of the vane will be had regardless of thespeed of travel of the car; the succession of emblem presentations tothe eye produced by the rapid substitution of one emblem face for thepreceding one, increases the illusion effect.

Obviously, changes in the details of c'on struction may be made withoutdeparting from the spirit of my invention and I do not care to limitmyself to anyparticular form or arrangement of parts.

What I claim is j 1. An ornament forthe caps of automobile radiatorscomprising an upright spindle, means for detachably securing the spindlein upright position on a radiator cap, and a two winged blade journaledon its transverse axis of symmetry on the spindle, the wings thereofbeing proportioned and arranged to cause rotation of the device when themachine on which it is mounted isadvancing,

said blades carrying the representation of a flag or emblem on each ofits opposite faces with the representation on each face limited to thedimensions of one of the wings and with the representation of one facecarried by a differentwing from that which carries the representation onthe opposite face of the blade. 7

2. An ornament for the caps of motor vehicle radiators comprising anupright spindle adapted to be secured to the cap to project thereabove,and a two-winged vane j ournaled on its transverse axis of symmetry onthe spindle, said vane having a configuration to cause rotation thereofby the advancing movement of the vehicle, the vane carrying marginalflanges at the top and outer edge of each wing, with the marginalflanges of a wing projecting substantially transverse to the generalplane of the wing and in the direction of its advancing face, wherebythe advance face of the leading wing will carry a pocket formationeffective to carry the vane through its revolutions.

In testimony whereof I aflix my signature 1n the presence of twowltnesses.
